When Was the First Industrial Robot Invented?
The modern industrial robot has revolutionized manufacturing processes, driving up efficiency and productivity while reducing costs and errors. But when was the first industrial robot invented?
The Genesis of Industrial Robotics
The invention of the first industrial robot can be traced back to the early 20th century. In 1928, English inventor John Barber patented the Televox, a robotic arm that could be controlled remotely via a telephone line.
| Timeline | Inventor/Developer | Contribution |
|---|---|---|
| 1928 | John Barber | Televox (remote-controlled robotic arm) |
| 1954 | George Devol | Unimate (first programmable industrial robot) |
| 1973 | Victor Scheinman | Stanford Arm (first electrically powered industrial robot) |
The Birth of the Programmable Robot
George Devol is widely credited with inventing the first programmable industrial robot in 1954. Named the Unimate, it was a hydraulically powered robot capable of performing repetitive tasks such as welding and assembly.
| Feature | Description |
|---|---|
| Degrees of Freedom | 4 |
| Payload Capacity | 250 kg (551 lbs) |
| Repeatability | ±0.025 mm (0.001 in) |
The Era of Electrically Powered Robots
In 1973, Victor Scheinman developed the Stanford Arm, the first electrically powered industrial robot. This breakthrough paved the way for lighter, more precise robots that could be used in a wider range of applications.
| Era | Characteristics | Examples |
|---|---|---|
| Mechanical | Hydraulic or pneumatic power | Unimate |
| Electronic | Electric power | Stanford Arm |
| Computer-Controlled | Microprocessor control | Today's industrial robots |
